Life has become a matter of performing rather than living. Jonna has been assigned to promote an author who writes about sex but she herself needs an outlet, a diversion from her perfect life. Soon, she finds herself falling into an unending cycle of sexual addiction as she begins a very unsafe affair with a young, indolent millionaire. As the affair continues, Joanna begins to see an insidious pattern, but can’t help herself. She misses work, drifts away further from her husband, and is threatened by her lover.
